BTW, I should add that such a scheme has the potential for bad side effects if
widely adopted (which seems unlikely) and if the error is not zero mean. It
probably requires most stations to have accurate clocks.

wsjtx seems to have all the information necessary to “crowdsource” the time
interval boundaries. For a portable station without GPS or Internet that could
really help. If wsjtx published the dt values via IPC messages then it could
be done outside wsjtx in a separate utility (i.e., figure

Thanks, Bill. My intuition came from thinking of power as the integral of the
magnitude squared of the signal over the time-frequency extent. I reasoned
that doubling the bandwidth should double the power, all else being the same.
But all else is not the same as you pointed out.

You're confusing the vibration of air with an electrical signal at audio
frequencies. The word &qu

Hi Mike,
that is not correct. The FT4 signal is one-tone GFSK. At any point in time
there is only one tone with constant amplitude. In this respect the difference
between FT8 and
I asked this question in response to the message on the Facebook group but
perhaps that is the wrong venue. FT4 acoustic bandwidth is nearly twice that
of FT8. With audio gain unchanged when switching from FT8 to FT4, I would
expect power out to almost double (or to saturate, etc.). This
Serving wsjtx with flrig works perfectly with my FT-450D. This was just what I
was looking for. SWR is displayed during transmit. Thanks again!

Mike et al.,
Thanks! This is great information. I’ll try it out this weekend.
